The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand the following specific embodiment and only for the present invention is described, is not used in and limits the scope of the invention.It should be noted that, word 'fornt', 'back', " left side ", " right side ", "up" and "down" that use is described below refer to the direction in accompanying drawing, and word " interior " and " outward " refer to respectively the direction towards or away from specific features geometric center.
As shown in the figure, a kind of polypropylene dust retracting device of the present invention, comprise water treatment case 3, in described water treatment case 3, there is water, the upper cover of described water treatment case 3 is removable cover, on described, be covered with air vent 2 and water falling hole 4, the front end of Fan pipeline 1 submerges in water by air vent 2, water treatment case 3 one sides are provided with delivery port 5, delivery port 5 is provided with drainage pipeline 6, drainage pipeline 6 outlets are flexibly connected filter bag 13, the internal layer of described filter bag 13 is polytetrafluoroethylpunched punched felt 14, melt spraying non-woven fabrics 15 is selected in middle level, outer form for glass fibre and 16 blending of aromatic series fiber, described filter bag 13 bottoms are placed on the bottom of remaining water tank 12, remaining water tank 12 upper openings, water pump 8 flows to the water in remaining water tank 12 in water treatment case 3 from water falling hole 4 by water pipe 7, between water pump 8 and remaining water tank 12, be provided with the first control valve 11, water pump 8 other ends are communicated with water source, between water pump 8 and water source 10, be provided with the second control valve 9.
During work, the front end of Fan pipeline 1 of the present invention enters in water treatment case 3 by air vent 2, the wind now taken out contains part moisture and polypropylene powder, and temperature is very high, water treatment case 3 sealings, can not allow water-fast polypropylene dust fly everywhere, time one is long, in water treatment case 3, just there is slowly surplus of water, polypropylene dust floats on the surface, water treatment case 3 one sides are provided with delivery port 5, delivery port 5 is provided with drainage pipeline 6, drainage pipeline 6 outlets are flexibly connected filter bag 13, can filter bag 13 be fixed on to drainage pipeline 6 outlets with iron wire or anchor ear 18, utilize the impact of buoyancy of water and air-flow, polypropylene dust is flowed into filter bag 13 from drainage pipeline 6, the shown mouth of a river 5 height are at water treatment case 3 one middle side parts, can not be too low, delivery port 5 is highly too low, a delivery port draining, polypropylene dust is on the water surface, do not discharge, do not have the effect of Chalk-dust filtering, after tested, delivery port 5 is positioned at the following 1-3cm of water treatment case 3 water level for best, described filter bag 13 internal layers are polytetrafluoroethylpunched punched felt 14, melt spraying non-woven fabrics 15 is selected in middle level, outer form for glass fibre and 16 blending of aromatic series fiber, there is high-wearing feature, filter effect is better, the advantages such as long service life, can allow water flow away, polypropylene dust is stayed 13 li of filter bags, filter bag 13 can more renew after having expired, on drainage pipeline 6, be provided with the 3rd control valve 19, even when work, also can change at any time filter bag 13, increase operating efficiency, reduce the possibility of scalding, the present invention is provided with water pump 8 water of outflow is back to use in water treatment case 3 again, for prevent water in water treatment case 3 due to evaporation or other reasons not enough, water pump 8 other ends are communicated with water source, can close the first control valve 11, open the second control valve 9 moisturizings, when the water level of water treatment case 3 is during higher than delivery port 1-3cm, close the second control valve 9, opening the first control valve 11 normally works.
The upper cover of water treatment case 3 of the present invention is removable cover, can change the rubbish of water, the inner alluvial of cleaning.
Water treatment case 3 of the present invention adopts stainless steel material to make with remaining water tank 12, because water treatment case 3 and remaining water tank 12 have water for a long time, can make in the course of the work water treatment case 3 and remaining water tank 12 non-corrosives, do not affect normal work, if water treatment case 3 gets rusty with remaining water tank 12, polypropylene dust can be polluted, and without collecting, is worth.
In order to observe at any time working condition, at described water treatment case 3 opposite sides, be provided with water level observation window 17, can observe water level situation, polypropylene dust is piled up situation and silt depth.
A kind of polypropylene dust retracting device of the present invention; simple in structure; easy to use; to originally be discharged into airborne polypropylene dust changes into and from water, carries out filtered and recycled; filter bag 13 good filtration effect, durable, not only protected environment; and collect the polypropylene powder of returning and can continue to use, saved resource.
The disclosed technological means of the present invention program is not limited only to the disclosed technological means of above-mentioned embodiment, also comprises the technical scheme being comprised of above technical characterictic.
